Pacific Continental Corporation Reports First Quarter 2013 Results

Loan Growth and Successful Acquisition Drive First Quarter 2013 Profitability

EUGENE, Ore., April 24, 2013 – Pacific Continental Corporation (Nasdaq: PCBK), the holding company of Pacific Continental Bank, today reported financial results for the first quarter 2013.

Recent highlights:

Century Bank acquisition

The Century Bank acquisition successfully closed on February 1, 2013. A summary of the assets and liabilities acquired through the transaction is provided in the financial tables accompanying this press release. System integration was successfully completed during the weekend of April 6, 2013.

Net income

Net income for first quarter 2013 was $2.5 million or $0.14 per diluted share compared to net income of $2.7 million or $0.15 per diluted share in first quarter 2012. Merger expenses related to the acquisition of Century Bank totaled $1.2 million in the first quarter and reduced net income by approximately $835 thousand or $0.05 per diluted share.

“Our first quarter results and completed acquisition of Century Bank demonstrate continued progress towards our strategic initiatives,” said Hal Brown, chief executive officer. “In addition to the Century Bank transaction, we enjoyed our fifth consecutive quarter of organic loan growth which resulted in margin expansion. These results and our future performance outlook support the board’s decision to once again increase the quarterly dividend,” added Brown.

Loan activity continues

Outstanding gross loans at March 31, 2013, were $950.8 million, up $79.5 million from year-end 2012. Of the $63.3 loans acquired from Century Bank on February 1, 2013, $62.6 million was outstanding at quarter end. The remaining $16.9 million of loan growth was attributable to organic growth experienced during the quarter and represents an annualized growth rate of 7.8%. The bank continues to expand its lending to health care professionals. At March 31, 2013, loans to dental practitioners totaled $280.0 million and represented 29.4% of the total loan portfolio, a growth rate of 3.4% during the first quarter and 25.6% over March 31, 2012. Out-of-market dental loans at December 31, 2012, were $90.2 million, up $11.3 million during the quarter and up $40.2 million over March 31, 2012.

“Our business model and focused strategy continue to achieve excellent results,” said Roger Busse, president and chief operating officer. “We are increasingly optimistic based on our strengthening pipelines in all markets that organic growth will continue throughout 2013,” added Busse.

Capital levels

In February 2013, the Company’s board of directors authorized a stock repurchase plan. The plan is authorized to repurchase up to 892,000 shares or five percent of the Company’s outstanding shares. The plan commenced on April 1, 2013 with the purchases to occur over the next 12 months. No shares were repurchased during the first quarter.

The Company’s capital ratios continue to be well above the minimum FDIC well-capitalized designated levels. At March 31, 2013, the Company’s Tier 1 leverage ratio, Tier 1 risk-based capital ratio, and Total risk-based capital ratios were 11.71%, 15.38% and 16.62%, respectively, as compared to 12.33%, 16.90% and 18.15% at December 31, 2012. The FDIC’s minimum well-capitalized designation ratios are 5.00%, 6.00% and 10.00%, respectively.

Classified assets, provisioning and loan statistics

Classified assets saw a small increase during first quarter 2013, which was primarily attributable to assets acquired in the Century Bank transaction. At March 31, 2013, classified assets totaled $58.4 million, an increase of $2.3 million from the end of the prior quarter. Classified assets acquired through the Century Bank acquisition, net of the fair value adjustment, totaled $5.8 million at quarter end.

Nonperforming assets, a subcategory of classified assets, totaled $24.7 million at March 31, 2013, or 1.71% of total assets, a decrease from December 31, 2012, and March 31, 2012, ratios of 1.92% and 2.72%, respectively. Nonperforming assets were comprised of $7.0 million of nonperforming loans, net of government guarantees, and $17.7 million in other real estate owned.

Loans past-due 30-89 days were 0.20% of total loans at March 31, 2013, compared to 0.30% at December 31, 2012. This is the fifteenth consecutive quarter in which this ratio was near or below one percent, a figure that suggests stabilization in the migration of problem loans.

“With the Century Bank acquisition and system conversion behind us, our expectation is that we will see further reductions in the level of classified and problem assets throughout 2013,” said Casey Hogan, executive vice president and chief credit officer. “This improvement should allow more resources for business development and growth initiatives as the year progresses,” added Hogan.

The Company’s first quarter 2013 provision for loan losses totaled $250 thousand compared to $1.3 million for first quarter 2012. The lower provision for loan losses reflects improving credit quality. During the first quarter 2013, net loan charge offs totaled $283 thousand compared to $62 thousand of net recoveries in fourth quarter 2012 and $412 thousand in net loan charge offs in first quarter 2012.

The allowance for loan losses as a percentage of outstanding loans at March 31, 2013, was 1.72% compared to 1.88% at December 31, 2012, and 1.92% at March 31, 2012. The decrease was partially attributable to the Century Bank acquired loans included at their fair value, net of any credit risk adjustments.

Core deposit growth slows

Period-end Company-defined core deposits at March 31, 2013, were $960.7 million and included $64.8 million of deposits acquired in the Century Bank transaction. Organically, outstanding core deposits declined during the first quarter 2013, which is a typical seasonal pattern for the first quarter. Average core deposits for the first quarter 2013 were $943.3 million compared to $900.4 million and $870.1 million at December 31, 2012, and March 31, 2012, respectively, with the increase primarily attributable to the acquisition of Century Bank core deposits. At period-end March 31, 2013, noninterest-bearing demand deposits totaled $314.8 million and represent 32.8% of core deposits.

Net interest margin

The first quarter 2013 net interest margin averaged 4.29%, a linked-quarter increase of 18 basis points over fourth quarter 2012, and a decline of 10 basis points from first quarter 2012. The increase in the linked-quarter net interest margin was attributable to three factors: 1) accretion of the Century Bank loan fair value mark which totaled $231 thousand; 2) reduction in the amortization of premiums on mortgage-backed securities due to lower levels of refinancing activity; and 3) improvement in asset mix as average loans increased to 65 percent of total average assets. The accretion of the Century Bank loan fair value mark during the first quarter 2013 positively impacted the net interest margin by 7 basis points. Consistent with previous quarter trends, the yield on loans and the cost of funds both continued to decline on a linked-quarter basis.

Noninterest income and expense

First quarter noninterest income was $1.3 million, down $172 thousand from first quarter 2012. The decline was primarily due to a drop in revenues from the origination of residential mortgages as this line of business was closed at the end of first quarter 2012. During the first quarter 2013, the Company also booked other-than-temporary-impairment expense of $16 thousand related to its holdings of private-label mortgage-backed securities.

Noninterest expense in first quarter 2013 was up $1.8 million and $2.1 million over fourth quarter 2012 and first quarter 2012, respectively. The majority of the increase in noininterest expense on a linked-quarter and year-over year basis was due to $1.2 million of merger related expenses in the Century Bank acquisition recorded during first quarter 2013. The Company also saw an increase in personnel expenses of $566 thousand, which was due to 2012 staff additions and personnel added in the Century Bank acquisition.

The first quarter efficiency ratio was 73.5%. Excluding first quarter merger related expenses, the efficiency ratio would have been 65.0%.
